Description

基于iOS操作系统的录音数据导入、备份方法及装置Recording data import and backup method and device based on iOS operating system

技术领域technical field

本发明涉及录音技术，具体涉及一种基于苹果移动(iOS，iPhoneOS)操作系统的录音数据导入、备份方法及装置。The invention relates to recording technology, in particular to a method and device for importing and backing up recording data based on an Apple mobile (iOS, iPhoneOS) operating system.

背景技术Background technique

苹果移动(iOS，iPhoneOS)操作系统作为苹果公司为iPhone、iPad、iPod等iOS设备开发的移动操作系统，由于可以兼容大量的应用软件，满足了不同用户的个性化需求，应用的用户越来越多；同时，随着信息科学技术的不断发展，用户在iOS设备上安装的应用软件也越来越多，使得iOS设备上的数据量迅猛增长。但由于iOS操作系统是一个封闭的操作系统，因此，应用开发者只能使用苹果公司对外公开提供的开发接口进行应用软件的开发，从而使得开发出的针对iOS操作系统的应用软件所能够实现的功能受制于提供的开发接口。例如，iOS操作系统中的录音软件对用户进行录音后，由于目前苹果公司并没有针对录音数据的导入和导出提供相关的接口，因此，iOS设备中录制的录音数据只能存储在iOS设备中，使得在需要对录音数据进行备份以提高录音数据安全性的场景下，录音数据的安全性较低；同时，外部设备录制的录音数据也无法导入到iOS设备，影响了用户业务的体验。The Apple Mobile (iOS, iPhoneOS) operating system, as a mobile operating system developed by Apple for iOS devices such as iPhone, iPad, and iPod, is compatible with a large number of application software and meets the individual needs of different users. The number of application users is increasing. At the same time, with the continuous development of information science and technology, users install more and more application software on iOS devices, which makes the amount of data on iOS devices increase rapidly. However, since the iOS operating system is a closed operating system, application developers can only use the development interface publicly provided by Apple to develop application software, so that the developed application software for the iOS operating system can achieve Functionality is subject to the provided development interface. For example, after the recording software in the iOS operating system records the user, since Apple currently does not provide a relevant interface for the import and export of recording data, the recording data recorded in the iOS device can only be stored in the iOS device. As a result, in scenarios where the recording data needs to be backed up to improve the security of the recording data, the security of the recording data is low; at the same time, the recording data recorded by the external device cannot be imported to the iOS device, which affects the user's service experience.

目前，对于非iOS设备，例如，固定终端设备，开发有一些软件，用于实现对非iOS设备中录音数据的导入和导出。例如，苹果的官方应用软件iTunes，或者第三方应用软件iTool，可以对非iOS设备中的录音数据进行导入和导出处理，其中，iTunes软件是一个免费应用程序，能播放所有的数字音乐和视频，iTools是一个用来同步iOS设备的电脑端软件。但由于iTunes以及iTool是基于OSX操作系统或windows操作系统，其中，OSX操作系统是苹果公司为Mac系列产品开发的专属操作系统，基于UNIX系统。由于接口的不同，因而，不能应用于iOS操作系统。因而，现有技术中还没有能够从iOS操作系统中导出录音数据、以及，将外部录音数据导入到iOS操作系统中的技术方案。Currently, for non-iOS devices, such as fixed terminal devices, some software has been developed for importing and exporting recording data in non-iOS devices. For example, Apple's official application software iTunes, or third-party application software iTool, can import and export recording data in non-iOS devices. Among them, iTunes software is a free application program that can play all digital music and videos. iTools is a computer-side software used to synchronize iOS devices. But because iTunes and iTool are based on OSX operating system or windows operating system, wherein, OSX operating system is an exclusive operating system developed by Apple for Mac series products, based on UNIX system. Due to the different interfaces, it cannot be applied to the iOS operating system. Therefore, there is no technical solution capable of exporting recording data from the iOS operating system and importing external recording data into the iOS operating system in the prior art.

The C/C++ conventional interface functions include: sqlite3_open(), sqlite3_prepare(), sqlite3_step() , sqlite3_column(), sqlite3_finalize(), sqlite3_close(). Among them, the SQLite database is a light-weight relational database that can support mainstream operating systems such as Windows/Linux/Unix. The system utilizes a client/server (C/S, Client/Server) two-tier The association, the client calls the unified C language API function (C/C++ conventional interface function), establishes a connection with the remote server through the Internet, the bottom layer of the server is associated with the SQLite database, and the client proposes a data access method, which is first taken over by the server. And the server submits the access methods one by one to the SQLITE database for processing, and then sends the processing results to the client by the server, because the server can be accessed by multiple user interfaces and supports network connections, so all client connections are taken over by the server and access, so that the SQLite database has a multi-user network access function.
